Free monad over a free functor of CopyInOp; abstractly, a computation that consumes
a org.postgresql.copy.CopyIn
and produces a value of type A
.
Syntax for CopyInIO
.
Sum type of primitive operations over a org.postgresql.copy.CopyIn
.
Catchable instance for CopyInIO.
Module of constructors for CopyInOp
.
Module of constructors for CopyInOp
. These are rarely useful outside of the implementation;
prefer the smart constructors provided by the copyin
module.
Suspendable instance for CopyInIO.
Suspendable instance for CopyInIO.
Lift a CopyInIO[A] into an exception-capturing CopyInIO[Throwable \/ A].
Non-strict unit for capturing effects.
Natural transformation from CopyInOp
to Kleisli
for the given M
, consuming a org.postgresql.copy.CopyIn
.
Algebra and free monad for primitive operations over a
org.postgresql.copy.CopyIn
. This is a low-level API that exposes lifecycle-managed JDBC objects directly and is intended mainly for library developers. End users will prefer a safer, higher-level API such as that provided in thedoobie.hi
package.CopyInIO
is a free monad that must be run via an interpreter, most commonly via natural transformation of its underlying algebraCopyInOp
to another monad viaFree#foldMap
.The library provides a natural transformation to
Kleisli[M, CopyIn, A]
for any exception-trapping (Catchable
) and effect-capturing (Capture
) monadM
. Such evidence is provided forTask
,IO
, and stdlibFuture
; andtransK[M]
is provided as syntax.
